ARP 94-01 Integra B18A1/B1 Main Stud Kit

Lock in your bottom end—so your B18 stays together under boost, RPM, and heat.

If you’re building (or refreshing) a 94–01 Acura Integra B18A1/B1, your factory main bolts are one of the easiest places for clamping force to fall short—especially as cylinder pressure climbs. This ARP main stud kit replaces them with race-proven hardware designed to deliver more consistent main cap clamping, improved durability, and confidence when you push your setup harder.

Why builders choose ARP main studs

• Stronger, more reliable clamping force than typical OEM fasteners—built to handle extreme load and vibration
• Premium alloy construction with ARP’s proven manufacturing processes for performance applications
• Precision fit for B18A1/B1 applications to support a clean, professional engine build
• Trusted in motorsports and serious street builds where “good enough” isn’t

Built with quality you can verify

ARP’s manufacturing is backed by disciplined quality systems with ISO 9001 and AS9100 registration, helping ensure consistent strength, fit, and reliability from batch to batch—so you’re not gambling on the most critical fasteners in your engine.

Best for: high-compression builds, boosted setups, track-driven Integras, and anyone who wants long-term bottom-end reliability on a B18A1/B1.
